Custom values for arch to use for cross-compilation


I am using Travis with OpenWatcom compiler even if it is not regulary supported.
I am using featur for “compiler” which can use custom value and this value is used in matrix.
Thanks this I can generate matrix with custom values which are propagated to environment variable.
In my case “compiler” -> “TRAVIS_COMPILER”.
But “arch” doesn’t behave similar way. I can use custom values for “arch” and they are used for matrix generation.
Problem is that these custom values are not reflected to “TRAVIS_ARCH” environment value.
Please, could you reflect custom values for “arch” to “TRAVIS_ARCH” environment variable, similar then for “compiler” behaviour.

TRAVIS_CPU_ARCH is the envvar reflecting the value of arch: See
